Will Transmission Fluid Deteriorate in 5 Years?

[LeGenesis]

Transmission fluid can deteriorate in 5 years. Here is relevant information about transmission fluid: 1. Manual Transmission Fluid: Automotive gear oils are classified into five grades (GL-1 to GL-5). GL-1 to GL-3 have lower performance requirements and are used for lubricating spur and bevel gears under normal loads, as well as gears in transmissions and steering systems. Manual transmission fluid generally needs to be replaced every 2 years or 60,000 kilometers under normal driving conditions. 2. Automatic Transmission Fluid: The specialized fluid used in automatic transmissions serves as both the hydraulic fluid for the torque converter and the lubricant for the planetary gear set, as well as the hydraulic fluid for the shifting mechanism. Automatic transmission fluid typically needs to be replaced every 120,000 kilometers under normal driving conditions, or every 60,000 kilometers under severe driving conditions.
